It’s very hard. That was the hard part for me (Peter), especially with Roger (red. Federer), because we did so many weeks together. We did 40 weeks. So basically, I had a relationship with him because I spent so much time with him. Further he was a kid when I worked with him. He was going from being kind of young in his mind outside the court growing into a man. So, it was a lot of work outside the court and also on court of course.

It was easy with Marat (Red. Safin) because by then he was more a man, so I didn’t have to focus so much on him as a person. It was strictly business. I didn’t travel as extensively with him as I did with Roger, so I had some time with my family.

Q: If you could provide yourself with an advice with what you know now, what would that be?

Don’t do too many weeks in a row. It’s hard to be away from the family for 5-6 weeks. It’s very, very hard. I prefer going away for 3 weeks and then have a block of 2 weeks at home and then go away again. Leading up to Grand Slam, you have to do a month. But in between the slams you have to have some breaks. 1 week is not enough as you come home, and you land. You feel all right. It’s nice to be home and then you have to go again. If you have 2 or 3 weeks at home, then you feel more like you can relax a little bit and take care of the family and do things together, because 1 week it’s simply too little.
